In the drawings, only those parts of a beaming or warping machine are shown, which are necessary for the understanding of the invention.

Referring now to Figs. 1-4, H! generally indicates the frame of a beamer according to the invention. The frame is composed of several parts in conventional manner.

As best shown in Figs. 3 and 4, a driving motor l2 mounted on a supporting member l4 inside the beamer is connected with a rotatable driving pulley 16 arranged outside the beamer. Said driving pulley I6 is connected with another pulley M3 by means of three belts 20. As best shown in Figs. 1, 2, 3 and 6, the driven pulley I8 is keyed to a driving shaft 22, rotatably arranged in roller bearings 24 of a bushing 26 mounted in an aperture 28 of a side wall 30 0f the frame [0. Said bushing 26 is secured to the side wall 30 by means of a plurality of screws. A roller 32 and a drivin pinion 34, forming an integral piece, are keyed to the end of the driving shaft 22, projecting from the bushing 26 toward the center of the beamer. As best shown in Figs. 1 and 4, a second bushing 36 is mounted on the opposite side wall 38 of the frame ll] of the beamer. A shaft 40, journalled in roller bearings of said bushing 36 is co-axially arranged with above mentioned driving shaft 22, journalled in the bushing 26. A second roller 42 is keyed to the shaft 40. As best shown in Figs. 1, 2, 3 and 6, a supporting member generally indicated by 44 is swingably mounted on a cylindrical portion 46 of the bushing 26. The axis of rotation of said supporting member 44 coincides with the longitudinal axis of the driving shaft 22. According to Figs. 1, 2, 3 and 8, said supporting member 44 is provided with a gear segment 48 in mesh with a pinion 59 secured by a pin 52 to a transverse rod 54 rotatably mounted in the side walls 30 and 38 of the frame I0.

In a similar manner, as best shown in Fig. 1, a second supporting member generally indicated by 56 is swingably mounted on a cylindrical porion of the bushing 36 in such a manner, that its axis of rotation is in line with the longitudinal axis of the shaft 40. Said supporting member 58 is provided with a gear segment 58 in mesh with a pinion 60 secured to the transverse rod 54 in any suitable manner. According to Figs. 1 and 4, a worm gear 62 keyed to a projecting end of the transverse rod 54 is in mesh with a self-locking worm 64 mounted at the lower end of a spindle 65, rotatably arranged in suitable bearings of the frame ill of the beamer. The upper end of said spindle 66 carries a hand Wheel 68, by means of which said spindle 66 may be rotated for lifting or lowering the pair of supporting members 44,56

through the medium of the gears 64, 62, 60, 58, 50, 48.

As best shown in Figs. 1, 2, 3 and 8, the supporting member 44 is provided with a hub 79. Likewise, the opposite supporting member 58 is provided with a hub 72. As best shown in Fig. 1, said hub 72 of the supporting member 56 is provided with spaced roller bearings 74, 76. A sleeve 78 is rotatably and axially immovably arranged in said roller bearings 74 and 76. A disc 80 serving as a brake drum is keyed to said rotatable sleeve 78 by means of a key 82. A rod 84 carrying a beam engaging means generally indicated by 86 is axially movably arranged in said sleeve 78. The beam engaging means 86 is provided with a nipple 88 for engagement with a bore 90 (see Fig. 4) of a fiange 92 of a beam generally indicated by 94. Furthermore, said beam engaging means 86 is provided with projections 96 on said nipple 88 for engagement with corresponding recesses 98 in the wall of the flange 92 of the beam 94. Moreover, three connecting pins I are rigidly connected with the disc-like portion I02 of the beam engaging means 86. Each of said connecting pin I90 is in slidable engagement with a bore I04 in the brake drum 80 so that the latter is positively connected with the beam engaging means 86 for a simultaneous rotation with the latter. As best shown in Fig. 4, the brake drum 80 is in contact with the roller 42 carried by the shaft 40.

In order to displace the rod 84 and the beam engaging means 86 mounted thereon toward and away from a beam 94, the following adjusting mechanism is arranged on the supporting member 56, as best shown in Fig. 1: A bracket I06 provided with a scale I08 is attached to the hub 72 by screws I I0. Said bracket I09 has two bores H2, H4 rotatably receiving a spindle II 6, prevented from axial displacement by its shoulder u H8 and a set collar I20. A hand wheel I22 secured to the spindle I I6 may be used for rotating same. A threaded portion I24 of the spindle H6 is in engagement with a threaded bore of an actuating member I26 having a lug I28 provided with a bore I80 in engagement with the rod 84. A roller bearing I32 is arranged on one side of said lug I28 and a roller bearing I34 is arranged on the other side of said lug I28. Set collars I36, I38 secured to the rod 84 and arranged adjacent said roller bearings I32, I34 prevent an axial displacement of the rod 84 relative to the lug I28 so that, in other words, the rod 84 and the beam engaging means 86 follow any movement of the actuating member I26 toward or away from the beam, which may be caused by a rotation of the spindle I24 by means of the hand wheel I22. A pointer I40 cooperating with the scale I98 on the bracket I06 may be used for setting the actuating member I26 and, of course, the beam engaging means 86 connected therewith, as described above, in any predetermined position.

In a similar manner, a sleeve I42 is rotatably, but axially immovably arranged in the hub 70 of the supporting member 44.. Said sleeve I42 carries a brake drum I44 and a gear I46 forming an integral piece. Said integral piece I 44, I46 is keyed to the sleeve I42 by a key I47. As best shown in Figs. 2, 3, and 8, the brake drum I44 is in contact with the roller 32, and the gear I 46 is in mesh with the driving pinion .34 secured to the driving shaft 22. As best shown in Fig. 1, a rod I48 carrying a beam engaging means I 50 is axially shiftably arranged in the sleeve I42. The beam engaging means I has a nipple I52 for engagement with a hole in the flange I54 of the beam 94. Projecting portions I56 on said nipple -I52 serve for engagement with corresponding recesses in the flange I54, so that the beam engaging means I50 may be positively connected with the flange I54 of the beam 94. Three connecting pins I58, rigidly connected with a disc-like portion I60 of the beam engaging means I50, are in slidable connection with bores I62 in the member forming the brake drum I44 and gear I46. Thus, the beam engaging means I50 is positively connected with the gear I46, so that it may be rotated for a rotation of the beam 94 when the gear I46 is driven by the driving pinion 34, connected with the motor of the beamei'.

The beam engaging means I59 may be displaced relative to the beam engaging means 86 toward and away from the beam 94 by an adjusting mechanism. Said adjusting mechanism comprises a bracket I64 provided with a scale I66 and attached to the hub 70. A hand wheel I68 is secured to a spindle I79 rotatably but axially immovably mounted on said bracket I64. The threaded portion of said spindle I70 is in engagement with a threaded bore of an actuating member I72 having a lug I74 provided with a bore receiving the rod I48 carrying the beam engaging means I50. A roller bearing I76 is arranged on one side of said lug I74, and a roller hearing I70 is arranged on the other side of said lug I74. A set collar I80 is secured to the rod I48 adjacent the roller bearing I76. Another set collar I82 secured to the rod I48 is arranged at a certain distance from the roller bearing I78, and a spring I84 is interposed between said set collar I82 and the roller bearing I78. A rotation of the hand wheel I68 causes an axial displacement of the actuating member I72 having a pointer I86 for cooperation with the scale I66 so as to permit an adjustment of the actuating member In in a pre-determined position. If the actuating member I72 is displaced in a lefthand direction, (as viewed in Fig. 1) the rod I48 and the beam engaging means I59 will follow such a movement of the actuating member I72,-

until the beam engaging means I50 engages the beam 94 preventing a further movement thereof in left-hand direction; thereupon, the spring I84 will be compressed, if the left-hand movement of the actuating member I72 continues. If the actuating member I72 is moved in right-hand direction, at first the spring I 84 will expand, if said spring was in a compressed condition, whereupon the rod I 48 and the beam engaging means I50 will follow the movement of the actuating member I72 in right hand direction.

The above described swingable support 44, 56 may be swung from its lower beam receiving position shown in Fig. 3 into its upper operative position shown in Fig. 2 by a rotation of the hand wheel 68 (Fig. 4) arranged on the spindle 66 (Figs. 1 and 4) carrying the worm 64 in mesh with the worm gear 62 keyed to the rotatable transverse rod 54 carrying the pinions 59 and 60 in mesh with the gear segments 48 and 58. A spring-loaded pawl I86 cooperating with a ratchet wheel I 90 mounted on the spindle 66 and the self-locking worm 64 prevent an undesired drop of the beam loaded support into a lower position thereof. Compensatin means or springs I92, I94 wound around the transverse rod 54 and connected with a stationary transverse bar I96 and the Pinion 60 and pinion 60 respectively are arranged for compensating the weight of the support carrying an empty beam.

The swingable support 44, 56 may be held in its upper operative position by means of the following locking means: A locking mechanism generally indicated by I98 (Figs. 1, 2 and 3) is arranged on one side of the beamer for cooperation with the supporting member 44, and a locking mechanism generally indicated by 200 (Fig. 4) is arranged on the other side of the beamer for cooperation with the supporting member 56. As both locking mechanisms I98 and 20B are of the same construction, only one of them, the locking mechanism I98, will be described hereinafter. A bracket 202 attached to the frame I by screws 204 is provided with a vertical bore 206. A plate 208 having a recess 2I9 is attached to the bracket 202 by means of screws 2I2. A bolt 2I4 slidably inserted into the bore 205 of the bracket 202 is provided with a head 2I6 carrying a supporting element 2I8, which may be moved upwardly and downwardly in the recess 2 I0 of the plate 298. The upper threaded end of the bolt 2M is in engagement with the threaded bore of a lockin knob 22!] resting on the upper surface of a portion of the bracket 202. The supporting element 2I8 carries a locking slide 222 provided with a longitudinal slot 224 in engagement with the bolt 2| 4. The locking slide 222 may be moved along the supporting element 2IB in a horizontal direction toward and away from the front side of the beamer. A spring 225 is interposed between the lower surface of a portion of the bracket 202 and the upper surface of the locking slide 222. When the swingable support 44, 5B is in the lower beam receiving position shown in Fig. 3, the supporting element 2 I8 and the locking slide 222 of the locking mechanism I98 are in the position shown in said Fig. 3. Thus, the locking slide 222 is out of the path of the supporting member 44, when the latter is lifted into the upper operative position shown in Fig. 2, wherein its edge 230 abuts against the bracket 202. When said supporting member 44 is in said upper operative position, the locking slide 222 may be moved toward the front wall of the beamer until the edge 228 of the slot 224 abuts against the bolt 2 I4. Thereupon, the locking knob 220 may be tightened whereby the supporting element 2I8 carrying the lockin slide 222 is lifted against the action of the spring 226, until the locking slide is firmly held against a recess 232 of the supporting member 44 and the edge 234 of the recess 2I0 of the plate 208 as shown in Fig. 2. Thus, the swingable support 44, 56 is firmly held in its upper operative position by means of the locking mechanism I98, 200, so that the support 44, 5B and the beam 94 carried by the support are not subject to undesired vibration during the operation of the beamer.

If it is desired to swing the support 44, 55 in its lower position after a Winding has been applied to the beam, the locking knob 220 is loosened whereby the locking slide .222 and its supporting element 2I8 are lowered under the action of the spring 226. At this time, the support 44, 56 will be held in an upper position by means of the pawl I88 in engagement with the ratchet wheel I90. After the disengagement of the locking slide 222 from the recess 232 of the support by means of above described loosening of the locking knob 220, the locking slide 222 may be readily moved into the position shown in Fig.

3, which is limited by an engagement of the edge 236 of the slot 224 with the bolt 2 I4. Thereupon,

6 after a release of the pawl I88 from the ratchet wheel I90, the swingable support 44, 56 may be readily lowered into the position shown in Fig. 3 by turning the hand wheel 08.

As the supporting member 44 is swingable about the axis of the driving shaft 22 carrying the driving pinion 34, the gear I46 positively connected with the beam engaging means I50 will be permanently in mesh with the drivin pinion 34, whether the supporting member 44 is in its lower position or in its upper position or in any intermediate position, as may be readily gathered from Figs. 2, 3 and 4. For the same reason, the brake drum I44 will be permanently in contact with the roller 32. Likewise, as the supporting member 56 is swingable about the axis of the shaft 40 carrying the roller 42, the brake drum 80, positively connected with the beam engaging means 86, will be permanently in contact with said roller 42. Thus, the rollers 32 and 42 being in engagement with the brake drums I44 and may act as supporting-rollers supporting said brake drums I44 and 80, which in turn support the shiftable rods I48 and 84 carrying the beam engaging mean-s I50 and 86 being under the load of the beam 94.

A brake band 238 (see Figs. 1 and 3) is arranged for cooperation with the brake drum I44. Furthermore, a brake band 249 (see Figs. 1 and 7) is arranged for cooperation with the brake drum 00. According to Fig. '7, the ends of the brake band 240 are mounted on a lever 242 swingably arranged on a stud 244 arranged on the stationary bracket 246 carrying the locking mechanism 200. According to Figs. 1, 4 and '7, the other end of said lever 242 is rotatably and adjustably connected with one end of a link 248, the other end of which is pivoted at 250 to a crank 252 rigidly connected with a transverse rod 254 rotatably arranged in the frame of the beamer. As best shown in Fig. l, a second crank 256 is secured to said rotatable transverse rod 254. Said crank 25% is pivoted at 258 to one end of a link 260, the other end of which is rotatably and ad" justably connected with one end of a lever 242.

As best shown in Figs. 1 and 3, said lever 252 carries the brake band 238 and is swingably mounted on a stud 264 arranged on the bracket 2 02 carrying the locking mechanism I98. Furthermore, as best shown in Figs. 1, 4 and 7, a gear segment 266 meshing with a pinion 298 keyed to the shaft of a torque motor 210 is secured to the rotatable transverse 254. The torque motor 270 is mounted on a bracket 212 attached to the frame of the beamer. A spring 2?! stretched between the gear segment 266 and the frame IE3 tends to hold the gear segment in the full line position shown in Figs. 4 and 7. When the beamer is in operation, above described braking mechanism is in the position shown in full lines in Fig. 7. When the torque motor 270 is energized for a stoppage of the beamer, the gear segment 266 is swung .into the position shown in dash and dot lines in Fig. '7, against the action of the spring 21 I, whereby the lever 242 carrying the brake band 240 is likewise brought into the dash and dot line position, so that the brake band 244 is applied to the brake drum 80. In the same manner, the brake band 238 will be applied to the brake drum H44, as the lever 262 carrying said brake band 238 is connected through the link 25% with the crank 256 secured to the rotatable transverse rod 254 actuated by a rockingmovement of the gear segment 266 driven by the torque motor 210.

As best shown in Figs. 1, 2 and 4, the beamer A bevel gear 292'keyed tosaid'transverse shaft 2 9035 in mesh with: a bevel gear 294 keyed to a spindle- 295 journalled'in suitable bearings of the frame III. Said spindle 296'may be rotated by means of a hand wheel 298 secured to the upper end thereof, so that the pressure roll 214 may be lowered for engagement with the beam 94 as shown in Fig. 4' or'rnay be lifted for clisengagement from said beam, as shown in Fig. 2.

In Fig. 4, 3% generally indicates a creel carrying a plurality of bobbins 342; Gnly the end portion of said creel Bill) is diagrammatically shown in Fig. 4. When the motor I2 is energized for rotating the beam '94-, yarns 304" drawnfrom the bobbins 302 are wound on the beam. The yarns 3M pass through a reed 30E mounted on the frame I and travel over a guiding roller 3 rotatab'ly arranged in bearings 3H! secured to the frame.

Above described beamer may be operated as follows: Assume the motor I2 is at a stand-still, the pressure roll 274 is in the position shown in Fig. 2, the support 44, G is in its lower beam receiving position shown in Fig. 3, and the beam engaging means are in the position I53 shown in dash and dot lines in Fig. 1.

Now, an empty beam 94 may be rolled on the ground into the space between the beam engaging means 8 5, I50. Thereupon, at first the right hand (as viewed in Fig. 1) hand wheel I63 is rotated, until the actuating member I'i2 reaches a pre-determined position relative to the scale I65. Such a rotation of the hand wheel I58 causes an axial displacement of the beam engaging means IEB for engagement with the flange I54 of the beam 94. Furthermore, during such a displacement of the beam engaging means I50,

the spring I84 between the roller bearing I78 and the set collar I82 may be compressed as soon as flange I54 of the beam 94 prevents a further axial displacement of the beam engaging means I563. Thereafter, the left hand (as viewed in Fig. 1) hand wheel I22 is rotated until the actuating member I26 reaches a pre-determined position relative to the scale I 08. Such a rotation of the hand wheel I22 causes an axial displacement of the beam engaging means 86 for engagement with the flange 92 of the beam 94. The pre-determined positions of the actuating mem-' bers I 23 and I12 relative to the scales I88 and IE6 respectively are selected in such a way, that the beam 94' may be held in proper registering position relative with the pressure roll. 214. The spring I34 takes care automatically of a slight displacement of the beam 94, if the beam was not placed exactly in register with the pressure roll 214 between the beam engaging means 86 and I56 prior to the engagement of the latter with the beam.

After the engagement of the beam engaging means 86 and I with the beam 94 by means of above described rotation of the hand wheels I22 and IE8, the swingable support, 56 may be lifted into its upper operative position shownin Fig. 2 bymeans of a rotation of the hand wheel 58 shown in Fig. 4. The support 44, 56 is locked in said upper operative position by means of'the locking mechanisms I98, 200 in the manner described above. Thereupon, the pressure roll 2T4 islowered by meansof a rotation of the hand whee1'298 from the'position shown in Fig. 2 into the position shown in Figs. 1 and 4, so as to come in engagement with the cylindrical main body of the beam 94. If a slight axial displacement of the beam 94 should still be necessary to have the beam in the-proper registering position with the pressure roll 214, such a slight axial displacement may be readily carried out by a slight rotation of the left hand (as viewed in Fig. 1) hand wheel I22 one way or the other. During such a slight rotation of the hand wheel I22 either the spring I84 will automatically urge the beam engaging means I56 and the beam 94 into the pro-per position or thespring I84 will besomewhat compressed.

Upon an energization of the motor I2; the beam 94 will be rotated through the belt drive I6, I23, 28, the pinion 34 in mesh with thegear I46, and by the beam engaging means I59 positively connected with said gear I46 through the connecting pins I53. The locking means I98, 20! firmly holding the swingable support 44, in its upper operative positionandthe spring I84 tightl urging the disc-like portions! 02 and IE0 of the beam engaging means 36 and I56 against the flanges 92 and I54- of the beam 94 eliminate an undesired vibration of the beam during the operation of the beamer, so that the latter may be operated at a high speed.

When, for any reason whatsoever, the operation of the beamer is to be stopped, the motor I2fis de-energized and the torque motor 276 is ener gized by an electrical control mechanism, which may be of any conventional construction. The energization of the torque motor 270 causes an immediate application of the brake bands. 238, Z llion the brake drums I 44', flfi positively con nected with the beam. engaging means 86 and 359 with the result of an immediate stoppage of the'beam 94'. After the stoppage of the beam 514, the torque motor 276 is automatically de-energized, so that the spring 2H may return the gear segment 266' into the full line position shown in the drawings for a disengagement of the brake bands 238 and 240 from the brake drums I44 and 80.

Now, after a release of the swingable support 44, 55 b rendering ineffective the locking means I98, 2%, the swingable support 44, 56 may be lowered into the position shown in Fig. 3, whereupon the beam engaging means 86 and I55 may be brought into the positions 85' and I58" for a release of the full beam 94.

The beam engaging means 86 and I56 shown in Fig. 1 are for use in cooperation with a beam having a hole on each of its flanges. There are also beams on the market, which are or" different construction.

Fig. 9, for example, illustrates a beam 94a having a nipple 3-I2a on its flange {32a and a nipple 3| 4a on its flange I54a. Furthermore, said beam is provided with an axle'3I 5a projecting from its nipple 3I4a. If the beamer, according to the invention, is to be used for such a type of beams 94a, the beam engaging means 86a carried'by the rotatable rod 84- and the beam engaging means I5a carried by the rotatable rod I48 are made-of a somewhat different construction. Furthermore, the rod 84 is provided with a recess MM and the rod I48 is provided with a recess 320a. Otherwise, all elements of the beamer may be of the same construction as shown in Figs. 18.

According to Fig. 9, the beam engaging means 86a comprises a disc-like member HlZa, rigidly connected with the rod 8 by welding, for example. Said disc-like member [920, has a recess 322a for engagement with the nipple 3l2a of the beam 94a. Furthermore, said disc-like member I02a. is provided with a plurality of holes 32%, which may be engaged with a, corresponding number of bolts 326a, screwed into the flange 92a of the beam 96a for a positive connection of the beam engaging means 86a with the beam 9441. A plurality of connecting pins 30a (only one being shown in Fig. 9) rigidly connected with the disc-like member IBM and slidably connected with the brake drum 8!] serve for a positive connection of the beam engaging means 860, with said brake drum 80. 7

Likewise, the beam engaging means l50a comprises a disc-like member ifilla rigidly connected with the rod 148 by welding, for example. Said disc-like member 16011 is provided with a recess 328a for engagement with the nipple Side of the beam 9% Moreover, said disc-like member i60a has a plurality of holes 330a for engagement with a corresponding number of bolts 332a screwed into the flange l54a of the beam 9 3a, whereby the beam engaging means Nita may be positively connected with the beam 94a. A plurality of connecting pins i581; (only one being shown in Fig. 9) rigidly connected with the disc-like member 160a are in slidable engagement with the gear I46 for a positive connection of the beam enga ing means I58 with said gear M5, which is driven by the motor of the beamer, as described above. The recess 32311 of the rod I48 receives the axle 3i6a of the beam 9 5a. In a similar manner, the recess 3I8a of the rod 84 would receive an axle of the beam, if such an axle would be arranged on the left hand side of the beam (as viewed in Fig. 9). The beam engaging means 86a and, IBM may be axially displaced relative to each other by means of the adjusting mechanisms associated with the rods 84 and M88, as described above in connection with Fig. 1. For example, the beam engaging means may be brought into the positions 86a and l50a for a disengagement from the bolts 324a and 330a of the beam 9411.

I have described preferred embodiments of my invention, but it is understood that numerous changes and omissions may be made without departing from the spirit and scope of the invention as set forth in the appended claims.

For example, the locking mechanisms I98 and 200 may be arranged for cooperation with a swingable support on a beamer, wherein the driving pinion is arranged for cooperation with a gear connected with the beam, and wherein said gear. is not permanently in mesh with said driving pinion. Likewise, the compensating springs I92 and I94 could be arranged on a beamer having a different type of driving connection between the motor and the beam.

What I claim is:

1.
